   Sounds like you have something installed that is not responding to =
messages which results in hangs in other applications waiting for a =
response.  If a non-responding app has a top level window it may show in =
the task manager applications tab as non-responding.  Otherwise, you can =
try to compile and run the app below.  It sends a message to each window =
and reports how long it takes it to respond.  This finds non-responsive =
windows.

  XP is starting to get flaky.  Explorer freezes; Outlook stalls after =
sending,
  etc.

  I'm _reasonably_ sure it's not a virus - I've got Vexira installed - =
or spyware
  - Spybot S&D.  Both are kept up to date.

  So.   I'd rather not wipe-and-reinstall, but I will if I have to, of =
course.

  Registry cleaner, or something?  Anyone got any favorites?

   Sounds
like you have =
something=20
installed that is not responding to messages which results in hangs in = other=20
applications waiting for a response.  If a non-responding
app = has a=20
top level window it may show in the task manager applications tab as=20
non-responding.  Otherwise, you can try to compile and run the
app=20 below.  It sends a message to each window and reports how
long it = takes it=20
to respond.  This finds non-responsive windows.
